Response with two Http Headers with the same Key

Hi, I am trying to set up a connection to a JSON-RPC server through the Mendix REST functionality. When I send a login request, I receive a response with several headers, such as ‘Set-Cookie’. This headers should be received twice (it is in for example Postman), one with the sessionid and one with a csrftoken.  However, in Mendix, only the first ‘Set-Cookie’ header can be found. Is there a way to access this second header?

Interesting scenario. If you can reproduce this in a test project (I would expose a simple API which just logs all headers and create a Postman request with multiple headers with the same name) you can submit a bug at
